Choice

Apple AirPods Pro 2
The Apple AirPods Pro 2 is a budget-priced OTC hearing aid that earned an A grade with a SoundScore of 4.0/5 in our lab testing, ranking #18 among 65 OTC hearing aids tested. At $249, it offers hearing assistance through Apple's familiar true-wireless earbud design. In our testing, the AirPods Pro 2 demonstrated strong performance in speech clarity during quiet listening situations, scoring 4.2/5—a full 1.38 points above the OTC category average. Music streaming quality is a standout strength at 4.4/5, exceeding the category average by 2.48 points and delivering strong linear fidelity for phone audio. Feedback handling earned a perfect 5.0/5, indicating excellent stability during movement. Speech understanding in noisy environments scored 2.3/5, which is above the category average by 0.77 points but remains mixed in absolute terms—users in challenging acoustic situations may find performance adequate rather than exceptional. Own-voice comfort is a limitation, scoring 1.9/5 and falling 0.61 points below the category average, which may result in noticeable occlusion effects when speaking. The AirPods Pro 2 is best suited for iPhone users seeking a discreet, multipurpose device that combines solid speech clarity in quieter settings with excellent music streaming. Those who prioritize own-voice naturalness or need stronger noise performance may want to explore alternatives.

MDHearing VoltMax
The MDHearing VoltMax is a behind-the-ear OTC hearing aid priced at $699, earning a B grade with a SoundScore of 3.0/5 in our lab testing. This places it in the lower tier of the OTC hearing aid category, ranking 62nd out of 65 devices tested. In our testing, the VoltMax delivered mixed results across key performance areas. Its standout strength is excellent feedback handling, scoring a perfect 5.0/5—above the category average by 0.46 points. This means users can expect stable performance without whistling or squealing during typical daily activities. However, speech clarity proved challenging, with speech-in-quiet scoring 1.9/5 (0.93 points below category average) and speech-in-noise at 1.0/5 (0.48 points below average). Own-voice comfort measured 2.4/5, slightly below the category norm. A significant limitation is music streaming, which scored 0.0/5—nearly 2 points below the category average. Users who prioritize phone streaming for calls or media should consider alternatives. The device features rechargeable batteries, offering convenience over disposable options. At this price point, several competitors deliver substantially stronger overall performance. The VoltMax may appeal to budget-conscious consumers who primarily need basic amplification with reliable feedback control and don't require streaming capabilities. Those seeking better speech clarity or music streaming should explore higher-scoring options in this price range.
